Feeding time is the best! GBB will eat anything, they don't seem to care about size as some T's do, and their very aggressive eaters.. I've watched my GBB ride a roach around the enclosure. The roach was just big enough that when the GBB raised up on tip-toe the roach could still get traction, after being drug for a bit the GBB just locked it's fangs in and took a ride. Didn't take but maybe 10 minutes for the venom to start working and the roach to collapse. Then it's weakened legs flailing around weren't a match for the GBB.
